I know this sounds like a crazy question but is this a rooster or a hen? I bought 5 buffs at a local auction about 2 months ago (they were pullets). They were labeled as hens but I think I might have 2 roosters.The chicken in the 2nd and 3rd picture is Cindy Crawford (might have to change the name to Charlie). She/he attempts to crow every morning and I haven't gotten any eggs yet. The chicken in the top pic is Uma Thurman (might change name to Bosely). I am very new to chickens and this is my first flock. Please help me determine the sex.
